Step 1 : Introduction to the question "Which of these aquatic terms is a palindrome?"
A palindrome is a word or sentence that reads the same forward as it does backward. Some examples of palindromic words are kayak, civic, radar, level, rotor, racecar, redder, madam, and refer. Some names are palindromes, such as the given names Hannah, Ada, Anna, Bob, and Otto. Palindromes can also consist of a sentence or phrase, e.g., "Mr. Owl ate my metal worm", "Do geese see God?", and "Was it a car or a cat I saw?" According to The Oxford English Dictionary the word is based on Greek root words meaning “back” and “running.”
